The following describes the technical solutions in the embodiments of the present application in detail with reference to the drawings in the embodiments of the present application.

In the course of treatment of female lower genital lesions, some specific drugs are required to be applied to the vaginal cervical mucosa or vulvar skin, so that the drug is absorbed on the local mucosal surface or skin to achieve a therapeutic effect. Because the cervical and vaginal mucosa and vulva tissues are covered by squamous epithelium, the squamous epithelium is thicker, and micro wounds are needed to be made on the surfaces of the cervical and vaginal mucosa in order to increase the absorption of the medicine on the surfaces of the vaginal and cervical mucosa in the medicine feeding process, the penetration and absorption of the medicine are facilitated, and thus, a better treatment effect is achieved. However, there is currently no device for making a micro-wound on a skin mucosa that is suitable for use in the lower genital tract.

In view of this, the present application has solved the above-mentioned technical problems by proposing a device for manufacturing a micro wound on a skin mucosa for the lower genital tract.

Referring to fig. 1 and 9, in view of the foregoing, the present application provides a device for manufacturing a skin mucosa micro-wound for a lower genital tract, so as to solve the above-mentioned technical problems.

Referring to fig. 1 and 3, a first embodiment of the present application provides a device for manufacturing a skin mucosa micro-wound for a lower genital tract, which is used for guiding a screw driver, and comprises:

a wound-making head 10, the wound-making head 10 having a fixing portion 11 and a piercing portion 12, the piercing portion 12 being for skin mucosa in a lower genital tract region to form a micro wound surface;

a universal adjustment mechanism 20, wherein the fixing part 11 is connected to the universal adjustment mechanism 20;

the universal adjusting mechanism 20 is arranged at the end part of the operating rod 30 and is in transmission connection with the operating rod 30;

The fixing part 11 on the wound manufacturing head 10 is connected with the universal adjusting mechanism 20 in a transmission way, and the puncturing part 12 on the wound manufacturing head 10 is used for the skin mucous membrane of the lower genital tract area to form a micro wound surface, so that the corresponding medicine can be absorbed and treated conveniently. In order to facilitate the multidirectional rotation of the wound manufacturing head 10 by medical staff, so as to form micro-wounds in different angle areas in the vagina, the universal adjusting mechanism 20 is arranged at the top end position of the operating rod 30 and is in transmission connection with the operating rod 30, and the medical staff can operate the universal adjusting mechanism 20 to rotate in a multidirectional manner through the operating rod 30 so as to drive the wound manufacturing head 10 to rotate in a multidirectional manner.

Specifically, before the medical staff performs the medication on the mucous membrane of the vaginal wall or the inner wall of the cervical canal, the medical staff directly stretches the puncturing part 12 on the wound manufacturing head 10 to the cervical surface or the target area of the vaginal wall to perform the puncturing operation locally, so as to manufacture the micro wound surface. The operation rod 30 can control the universal adjusting mechanism 20 to rotate and rotate the puncturing part left and right so that the puncturing part 12 can adapt to different angle areas in the vagina space, and the manufacturing of micro wounds at different positions is convenient.

In particular, the medical practitioner may position wound-making head 10 within the vagina until the puncture 12 in the wound-making head 10 reaches the target area of the endocervical wall or mucosal site of the vaginal wall. The medical staff then controls the universal regulating mechanism 20 to rotate and/or rotate left and right (or back and forth) through the operating rod 30, so that the puncture part 12 punctures the vaginal wall mucous membrane and a plurality of areas of the inner wall of the cervical canal to form a small micro wound surface, thereby facilitating the follow-up medical staff to apply medicine to the micro wound surface, for example, the micro wound surface is manufactured on cervical and vaginal wall mucous membranes in the medicine applying process of using red nocardia cell wall skeleton to treat HPV continuous infection, and the medicine absorption is increased. In the application process of photodynamic therapy of leukoplakia vulvae or squamous intraepithelial lesions of vulva, micro-wound surfaces are manufactured on the areas of the external vulva skin lesions, so that absorption of the lesions to the medicine during subsequent photodynamic medicine application is increased, and the treatment effect is improved.

It will be appreciated that the lower genital tract of the present application may be configured as a disposable medical device using a skin mucosa micro-wound manufacturing apparatus.
